Moparmatt72, I'm not really sure on that one, I know for a fact, that it helps to realign molecules in metals & strengthen them, I'm not sure if it would make it more brittle/too stiff with-out any flexibility &/or more prone to cracking/breaking or not, my guess would be it would help/be beneficial... But that is just a guess.... Need to talk to a metallurgist, my engineering back ground is Architecture/Drafting Design {construction/building related} & Utility Truck Building, Aerial Equipment, Golf Equipment Mfgrs. use it as a widely excepted practice, to strengthen club heads so the can make them very thin & light to move the weight were they want it, also to have elasticity & rebound capabilities {spring like COR efficiency}... I know that some brake companies do it to disc brake rotors, Crager claims it last way longer & is way harder, under severe usage, I have some Cryogenic treated slotted & drilled front disc brake rotors on my 2002 F350 dually, good so far 95K miles...
